CARBURETER.

SPECIFICATION forming part of Letters Patent No. 583,126, dated May 25, 1897.

Application filed November 8, 1895. Renewed September 24, 1896. Serial No. 606,885. (No model.)

To all whom it may concern:

Be it known that I, BAINBEIDGE L. RYDER, a citizen of the United States, residing at San Jos, county of Santa Clara, State of California, have vinvented an Improvement in Oarbureters; and I hereby declare the following to beY a full, clear, and exact description of the same.

My invention relates to that class of' vaporizers or gas-generators especially adapted for use in connection with explosive engines, and in which the gasolene or other vaporizable liquid is supplied to an absorbent material through Which the air is drawn, whereby the liquid is vaporized and the proper explosive mixture is formed.

My invention consists in the novel construction of the vaporizer, which I shall hereinafter fully describe, especial importance being laid upon the automatic feature of the device, by which a stated quantity or volume of vaporizable liquid is maintained, resulting in a uniform quality of explosive mixture, which quality it is the object of my invention to attain.

Referring to the accompanying drawing,the figure is a vertical section of my vaporizer.

A is the shell or casing of the vaporizer. B is its cap, secured thereto by suitable means, and O is a holding-ring within the casing or shell and having a diameter sufficiently less than the interior diameter of said shell to leave an annular or circumscribing space a around the ring between its periphery and the inner surface of the shell. The ring is open at both ends, and its length is sufficiently shorter than said shell to leave an underlying space a'. The ring is supported within the shell in suitable manner, the bestmeans for supporting it being that here shown, and consisting of a flange b, extending downwardly from the cap B, and internally threaded to receive the externally-threaded upper end of the ring O, whereby said ring is suspended from the flange. A screen D lies in the upper portion of the ring, and an outlet-pipe E issues from the top of the casing through its cap B.

The bottom of the casing is depressed or recessed to form a Well d2, and this Well is guarded and surrounded by a protecting shield or tube F, the lower portion of which is apertured, as shown at f, to afford communication with the well a2, and its upper end is fitted with a screen f.

G is the inlet for the gasolene or other vaporizable liquid, said inlet being controlled by a valve g, the stem g of which extendsinwardly through the inlet G and is tted with a controlling-springg2, the tendency of whichis to keep the valve g closed.

Within the protecting shield or tube F and operating within the Well a2 is a float H, the stem h of which is pivoted at 7L' and has an actuating-arm h2, Which bears against the inner end of the valve-stem g.

I is the air-inlet, which communicates with the circumscribing space a Within the shell.

The holding-ring C confines a body of absorbent material, (represented by J,) and it may consist of any suitable absorbent substance, as, for example, sponge. This absorbent material extends betweenv the screen D and the bottom of the shell, filling the lower space a' in said shell, but the liquid-well a?, with'its float H, is protected from the absorbent material by the shield F,which thus keeps the well entirely free to permit the automatic operation of the float and through it of the liquid-inlet valve g.

The operation of the vaporizer is as follows: When there is no liquid in the well a2, the float H sinks, and thereby causes its arm h2 to press upon the valve-stem g and to force and hold the valve g open. Thereupon the vaporizable liquid passes in through the inlet G into the space a and through the apertures f and the shield F into the Well a?. It saturates the absorbent material J throughout its entire bulk, and as the level of the liquid rises in the well a2 it lifts the iioat H, which thus removes its arm h2 from the valvestem g' and permits the spring g2 to close the valve g. This closing is effected when the vol- -ume of vaporizable liquid admitted is sufficient for vthe needs of the vaporizer. When this volume decreases, the inlet-valve gis automatically opened bythe sinking of the float II, and the volume is again brought up to the required standard by the admission of more liquid.

The air, passing in through the air-inlet I,

IOO

iiows down through the circumscribing space a and, passing through the absorbent material J, is drawn out with its mixture of gas or vapor from the device through the outlet E. Thus the required amount of vaporizable liquid is maintained and the explosive mixture resulting is uniform under all circumstances.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A vaporizer consisting of a shell or casing having a well in its bottom, a holdingring therein, open at both ends, having a diameter suiiiciently less than the diameter of the casing, to leave a eircumscribing` space, and having a length shorter than said casing to leave an underlying space, said ring being exteriorly threaded at its upper end and having a screen at said upper end, a mass of absorbent material within the ring, a guard resting upon the bottom of the shell or casing and surrounding the well therein, having its upper end open and provided with a screen and its lower end provided with apertures, a cap for the casing to which the upper end of the ring is screwed, with a pipe leading from said cap, an inlet for air, an inlet for the vaporizable liquid, at the lower portion of the shell, a valve controlling the ilow of liquid, having an inwardly-projecting stem, horizontjallyv disposed, a spring on said stem tending to hold the valve normally closed, and means foropening the valve against the power of its spring when the amount of liquid in the well'decreases.

2. A vaporizer comprising a shell, having within its lower portion a recess or depression for the vaporizable liquid, and a protecting-shield around said Well having its bottom apertured and its top provided with a screen, a cap for the casing having adownwardly-extending iiange, and an outlet-pipe passing through said cap, a holding-ring suspended from the ange of the cover and having a screen-top, said holding-ring having a diameter sufficiently less than that of the shell or casing to leave a circumseribing space and a length sufficiently less than that of the casing to leave an underlying space, absorbent material contained within said ring and underlying space, an inlet for the Vaporizable liquid for directing it to the absorbent material and into the well, a valve controlling said inlet, a float within .the well and intermediate connections whereby the movement ot the float automatically operates the valve, and an air-inlet through the easing and communicating with the circumscribing space around the holding-ring, whereby said air is directed downwardly to the absorbent material.

In witness whereof l have hereunto setmy hand.
